O 80 UNF screw is the screw’s size according to UNF standard, so the 0 80 UNF screw is also called #0-80 thread screw. The standard designation for a UTS thread is a number indicating the nominal (major) diameter of the thread, followed by the pitch measured in threads per inch. For diameters smaller than 1⁄4 inch, the diameter is indicated by an integer number defined in the standard; for all other diameters, the inch figure is given.. When the diameter smaller than 1/4", the value is indicated by a number, like #1 or No.1. 2.Thread sizes in metric are specified by diameter and pitch. The metric thread sizes are generally expressed as M2 × 0.25, the thread diameter is 2mm and pitch is 0.25mm. More difference between UNF thread and UNC thread are as following: 1)The UNF threads have smaller helix angle and better tightness, and it is more conducive to the self-locking of the thread. Therefore, it’s not that easy to be loosen compared with UNC threads. Here are the standard thread sizes and constraining geometries recommended by Xometry. Internal Threads Thread Hole Diameter(in) Max Thread Depth(in) UNC/UNF 0. UNF. UNF stands for ‘Unified Fine’, which is also a popular thread in the United States. UNF fixings are often used in the automotive and aerospace industries industry because of the requirement for tight, fine threads. UNF fasteners are typically made from steel or stainless steel fasteners. Features include better torque locking and load.

The external thread is a 3/8-24 UNF class 2A. They assume that the internal thread must have the same 2A class of fit as the external thread they presently manufacture. Based on this assumption, they contact their gage distributor / manufacturer and order a 3/8-24 UNF 2A plug gage. The only 2A plug gage that exists is a setting plug. Thread Repair Kits. Enable you to carry out fast and efficient repair of damaged or stripped threads. Recoil offer a huge range of insert sizes from 2mm diameter up to 100mm and in virtually all thread forms including METRIC, UNC, UNF, BSC, BA, BSP and BSW. We also stock rarer thread forms such as National Pipe Taper (NPT).

UNF Thread ANSI/ASME B1.1. UNF - Unified National Fine Thread. Similar to UNC. UNC and UNF threads are the choices for the customary screws and nuts. The thread angle is 60°. Advertising: Nominal. Diameter. Locknut Thread per ANSI/AFBMA 8.2. M-series Coarse Pitch; Size Range: M1 thru M68 Metric Thread. M-series Electrical Conduit Thread. M-series Fine Pitch Size Range: M1 thru M28 Metric Thread. M-series Fine Pitch; Size Range: M30 thru M64 Metric Thread. N-series (obsolete) External Thread.. Standardised in 1918. Angle of Thread 60°. American threads consist of two common thread patterns known as U.N.F and U.N.C. U.N.F [national fine] is exactly the same as the old S.A.E [standard american engineers] that existed before threads were unified. U.N.C [national coarse] roughly derived from the British Whitworth having the same pitches except 1/2 in dia where Whitworth is 12tpi and U.N.C is 13 tpi.. when ordering taps please specify the diameter and pitch and style of tap example.

Unified Thread Size Charts. The Unified Thread Standard (UTS) defines a standard thread form and series—along with allowances, tolerances, and designations—for screw threads commonly used in the United States and Canada.It is the main standard for bolts, nuts, and a wide variety of other used in these countries. It has the same 60° profile as the ISO metric.
